ASH-PIT FOR FURNACES.

SPECIFICATION forming part of Letters Patent No. 347.522, dated August17 1886.

Application filed May 1, 1886. Serial No. 200,772. (No model.)

.To @ZZ whom it' may concern:

Be it known that I, (JHARLEs T. ScHonN, a

citizen of the United States, residing at Philar ally also thedraft-inlet, and hence in order to insure a good draft this pit must bekept clean, which in former inventions could only be done by frequentattendance and use of a shovel to remove the ashes. Furthermore,whenashes are allowed to pile up under and in contact with the grate, theirheat has a very injurious effect upon the grate itself, burning it outmore rapidly and choking the draft. The removal of hot ashes to bins orbarrels is a fruitful source of fires. The manual labor required inshoveling out ashes under old plans, and the dirt and 'dust incident tosuch plans, have been always a serious drawback to furnaces for heatingdwellings. These objections, so far as I am aware, have obtained againstfurnaces heretofore used, and the purpose and end of my invention is toovercome them.

My invention therefore consists of a furnace which clears or cleansitself of ashes as they are made and conducts them to a receptacleoutside of the furnace, whence and in which they may be removed from thebuilding, all as I will now proceed to particularly set forthand claim.

In the accompanyingdrawings, in the two figures of which like parts aresimilarly designated, Figure 1 is a perspective View of sufficient of abricked furnacefor house-warming purposes to illustrate my invention,and Fig. 2 is a vertical section.

The furnace may be of any approved construction throughout; but beneathits grate a, I arrange a chute, b, highest at its inner end and theinner end of the grate, and incliningdownwardly and outwardly to thefront door, c, of thefurnace, so that the ashes as they are made falldown this inclined chute and are carried away from beneath the grate,and consequently their accumulation under the grate is prevented. Thischute has the closed rear wall, d, and the closed sides e, and its mouthf projects to a level with or slightly beyond the door to prevent theashes from falling off the chute and direct them out of thefurnace. Thisconstruction, therefore, insures proper draft to the grate.

In front of and outside the furnace, and in line with the chute, isarranged an under ground pit7 g, to contain an ash-pan, h, whichreceives the ashes as they come from the chute.

This pit is covered by a door, il, hinged at j toward its rear end, soas to leave a projecting portion, 7c, extending into the chute. Whenv'the door z' is raised, as in full lines, Fig. 2, to

gain access to the ash-pan for its removal, then its projecting portion7c extends across the mouth of the chute vertically, and closes itagainst the escape of ashes until the pan may be emptied and replacedand the door closed again. The door i may be pivoted in a inetallicframe, Z, surrounding the mouth of the pit g, as indicated in thedrawings, and said door may also be provided with a ring, m, foroperatingit. The chute is made of iron plate, and hence increases theheat-radiating surface ofthe furnace, its capability of4 self-cleaningalways leaving it free of ashes. The incoming draft, however, keeps itat such a temperature as to preclude its being burned out by the-heatfrom the grate.

An additional very great advantage of this selfcleaning ash-pit is thatit prevents the banking up of ashes beneath and in contact with thegrate, and so prevents the burning out of the grate from beneath. Bymeans of my self-cleaning ash-pit, also, the draft tothe fire is alwaysfree and unobstructed, and the fire may thus be kept bright and fresh.The ashes may be discharged directly into the pit and removed therefromwith a shovel as the pit is filled.

I do not claima stove or astove attahment or adjunct having the wall ofthe stove or a partition therein back of the grate inclined to dischargethe ashes into the ash-pit. In my invention the chute is constructed asan article of manufacture that may be applied to the grateframe entirelyindependent of the walls IOO l of the heater, and to any kind of heater,and so, also, the ash-pit is independent of the furnace or heateritself. A

l. The combination,with a furnacevgrate, of a combined inclinedair-induct and ash-discharge chute arranged directly beneath and connected with such grate, and slanting from its rear toward its front, andhaving its discharge end at the front, and an ash-pit at such dischargeend arranged outside of and away from the furnace, and a hinged coverfor said ashpit, serving also as a cut-off for the chute, substantiallyas described.
